AUTOMATIC GRAIN-WEIGHER AND REGISTER.

SPECIFICATION forming part of Letters Patent No. 331,962, dated December 8, 1885.

Application ti ed April 6, 1885.

To aZZ whom, it may concern:

Be it known that we, Isaac N. GRIFFITH and CARY F. GRIFFITH, of Macomb, in the county of McDonough and State of Illinois, have invented a new and useful Automatic Grain-\Veighing and Registering Machine, of which the following description will enable others skilled in the art to make and use the same, reference being bad to the accompany- Ic ing drawings, and to the letters of reference marked thereon.

This invention consists in the construction of an automatic grain-weighing and registering machine, which can be attached to all kinds of grain-thrashers or shelling-machines, and in such a manner that the clean grain, as it leaves the thrasher or sheller, will pass through .the machine, which automatically, by means of the weight of the grain, weighs 2 and registers the number of pounds or bushels, as may be desired; and its novelty is fully described in the following description, and pointed out in the claim.

In the drawings, Figure 1 is a perspective View. Figs. 2, 3, and 4 are sectional views of the same.

Similar letters of reference represent like parts in each figure.

B represents the frame or body of the ma- 0 chine, to which all the parts and mechanism are attached, of which A represents a revolving grain-receptacle, which is constructed with two heads, and divided into three compartments, 8 s s, curved in form. (See end View, Fig. 3.) A shaft passes through the center and forms bearings at each end, to which, at the front end, a threetoothed cogged wheel, a, is attached.

The front head has three projecting pins, 0 m m, attached to it. These pins are placed in such a position that when they rest on the end of the beam y one of the grain-compartments 8 is in the right position to receive the grain.

The weight P is adjusted on the graduating beamyto the number ofpounds thatis required to make a half or a bushel of grain, as may be required, and when the right number of on the dial N by the pointer 9.

pounds has been let into the con'lpartment the weight of the grain, by means of the projecting pin m, presses down. the inner end of the beam :1 sufficient to let the filled compartment pass underneath, where it empties into suitable receivers. This movement brings an empty compartment in place or position to be filled, and the same operation is continued as long as may be desired. At each one of the movements made in weighing the grain one of the cogs on the wheel a catches into one of the teeth in the wheel 0, and turns it one- 63 twentieth of its circumference.

Attached to the wheel 0 is an extended arm, Z, which, at every revolution of the wheel 0, catches into one of the teeth of the wheel n, and turns it one'tenth of its circumference.

Attached to the shaft of the wheel at is an extended arm, J, which, at every revolution of the wheel 11, catches into one of the teeth in the wheel (I, and turns it one-twentieth of its circumference. At the outer end on the same shaft is attached the pointer g.

i i and 0 are lock spring-bars, which hold their respective wheels in position, keeping them from turning backward.

The wheel 0 is rigidly attached to the shaft r, and the wheel d is loosely fitted by means of a metal sleeve, (see Fig. 4,) which passes through the side of the frame B, and has the pointer 0 attached, the pointer f being attached to the shaft r. At each revolution of 8c the wheel 0 the pointer f registers twenty on the dial M, and, by means of the arm Z, one At each revolution of the wheel a the pointer g registers ten on the dial. N, and, by means of the arm J, one on the dial M, designated by the pointer c. This indicates that the wheel 0 had made ten revolutions. The pointers are all set to 0 before commencing operations.

This manner of construction of the register- 9c ing mechanism of the machine is easily understood, and the number of pounds or bushels can be ascertained in an instant.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

weight P, in combination with the registering In automatic grain-meters, the receptacle N, substantially as shown and described, for A, divided into three apartments, 8 s 8, each the purpose set forth. apartment liavin a semicircle bottom, wheel T i 1 rw a, having three c ogs, graduating beam :1 and ggg g' mechanism, composed of wheel 0, having arm \Vil'nesses: Z, attached to the Wheel n, arm J, Wheel d, T.
